15. Um corpo de pequenas dimensões e de 50 kg de massa encontra-se sobre um plano horizontal liso e desloca-se com velocidade escalar constante e de módulo igual a 10 m/s . Em determinado instante, aplica-se a esse corpo uma força vec F , horizontal e oposta ao movimento que o corpo estava descrevendo, com intensidade igual a 100 N. O corpo somente realiza movimento de translação. Determine, em unidades SI: a) a distância percorrida pelo corpo ao fim de 2,0 s, con tados a partir do instante em que se aplicou a força F; b) o intervalo de tempo gasto para que o corpo pare, con tado a partir do instante em que se aplicou a força vec F . 1
